The cheeses might be contaminated with Shiga toxin-producing E. coli, (STEC).

According to the Food Standards Agency (FSA) symptoms of STEC can sometimes include a condition known as haemolytic uremic syndrome (HUS) - which can lead to kidney failure and can be fatal.

Other symptoms are severe diarrhoea (including bloody diarrhoea), abdominal pain.

In rare cases the infection can also cause complications, such as meningitis.

The (FSA) announced the recall on Christmas Eve. All sizes of the cheeses are affected, including individual portions that may have been included on grazing platters, it said.

"It may not always be clear whether you have purchased an affected product," the agency warned.

If in doubt, people are advised to contact the shop where they bought the cheese to find out, and in the meantime to not eat the cheese.
